Everybody loves beaches, the cool breeze, the shore, the sand and so on but the aftermath of beaches are very painful as you experience sunburn after it. So, according to a recent study the best medicine for sunburn is Vitamin D.
Vitamin D soothes your skin, high doses of Vitamin D can reduce the swelling, redness of skin, the pain, inflammation. According to double-blinded, placebo-controlled clinical trial out of Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center.
In the study, 20 participants were randomized to receive a placebo pill or 50,000, 100,000, or 200,000 IU of vitamin D one hour after small UV lamp “sunburn” on their inner arm. Researchers followed up with the participants 24, 48, 72 hours and 1 week after the experiment and collected skin biopsies for further testing.
Participants who consumed the highest doses of vitamin D had long-lasting benefits, including less skin inflammation 48 hours after the burn. Participants with the highest blood levels of vitamin D also had less skin redness and a jump in gene activity related to skin barrier repair.
“We found benefits from vitamin D were dose-dependent,” said senior author Kurt Lu. “We hypothesize that vitamin D helps promote protective barriers in the skin by rapidly reducing inflammation. What we did not expect was that at a certain dose, vitamin D not only was capable of suppressing inflammation, it was also activating skin repair genes.”

The trial is the first to describe acute anti-inflammatory benefits from taking vitamin D. According to the authors, despite widespread attention given to vitamin D deficiency, “there is a lack of evidence demonstrating that intervention with vitamin D is capable of resolving acute inflammation.”
By measuring gene activity in the biopsies, the researchers also uncovered a potential mechanism behind how vitamin D aids skin repair. The results suggest vitamin D increases skin levels of an anti-inflammatory enzyme, arginase-1. The enzyme enhances tissue repair after damage and helps activate other anti-inflammatory proteins. The study may have people flocking to vitamin supplement aisles, but Lu stresses that the trial tested very high doses of vitamin D that far exceed daily allowances.The results are published in the Journal of Investigative Dermatology.
